V. Orestis Papadigenopoulos

PhD Student in Computer Science

I am a PhD student at the Department of Computer Science at The Univeristy of Texas at Austin, supported by the Provost's Graduate Excellence Fellowship. I am fortunate to be advised by Prof. Constantine Caramanis . I am broadly interested in the field of theoretical computer science with emphasis on the design and analysis of (approximation and online) algorithms, online learning/ multi-armed bandits and combinatorial optimization. Prior to joining UT, I had the luck to be advised by Prof. Dimitris Fotakis.
